This book contains papers presented at the Second International Conference on Algebra, held in Barnaul in August 1991 in honor of the memory of A. I. Shirshov (1921--1981). Many of the results presented here have not been published elsewhere in the literature. The collection provides a panorama of current research in PI-, associative, Lie, and Jordan algebras and discusses the interrelations of these areas with geometry and physics. Other topics in group theory and homological algebra are also covered.

The ICRA VII was held at Cocoyoc, Mexico, in August 1994. This was the second time that the ICRA was held in Mexico: ICRA III took place in Puebla in 1980. The 1994 conference included 62 lectures, all listed in these Proceedings. Not all contributions presented, however, appear in this book. Most papers in this volume are in final form with complete proofs, with the only exception being the paper of Leszczynski and Skowronski, Auslander algebras of tame representation type, that the editors thought useful to include.

The Second Edmonton Conference on Approximation Theory, held in Edmonton, Alberta, June 7--11, 1982, was devoted to Approximation Theory and related topics, including spline approximation, computational problems, complex and rational approximation, and techniques from harmonic analysis and the theory of interpolation of operators. In conformity with the requirements of this series, this volume consists of refereed papers by a selection of the invited speakers. The conference was sponsored by the Canadian Mathematical Society and supported by grants from the Natural Sciences

Human Computer Interaction (HCI) is concerned with every aspect of the relationship between computers and people (individuals, groups and society). The annual meeting of the British Computer Society’s HCI group is recognized as one of the main venues for discussing recent trends and issues. This volume contains refereed papers and reports from the 1995 meeting. The materials cover a broad range of HCI related topics, including visualization, computer supported communication, task analysis, formal methods, user support and cyberspace. The documents consider both research and commercial pe
